CURRYING IVIACHINE.

SECIFICATION forming part of Letters Patent No. 649,487, dated May 15,1900.

Application filed January 15,1900. Serial No. 1,422.

To all whom it' 11m-3,' concern:

Be it known that l, LUDWIG C. SCHNEIDER, a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee and State ofWisconsimhave invented certain new and useful Improvements inCurrying-Machines; and I do hereby declare that the following is a full,clear, and exact description thereof.

My invention has for its object to provide a simple, economical, andefficient machine especially designed for rapid removal of spongyleathersubstance from the flesh side of tanned fur-skins in order to reduceweight of said skins and give them uniform thickness,as well as a smootheven iiesh-side surface, said invention consisting in certainpeculiarities of construction and combination of parts hereinafterparticularly set forth with reference to the accompanying drawings andsubsequently claimed.

Figure l of the drawings represents an end elevation of my machine,partly broken away and partly in section; Fig. 2, a front eleva; tion ofthe machine, partly broken; and Figs. 8 and 4, detail views of a portionof a raspface rotatory cylinder that constitutes an important element ofsaid machine.

Referring by letter to the drawings, A indicates each of a pair ofstandards to which are connected the front and rear side boards B of ahousing that converges above said standards toward a rotatory hollowsteel cylinder C, the face of which is rasp toothed throughout andexposed above the housing, the latter being extended beyond eachstandard and embodying arches l), flush with the cylinder adjacent tothe ends of same. The standards and housing constitute the frame of themachine, and the length of the cylinder approximates the distancebetween said standards. The rear upper inclined portion of the housingis preferably a metal plate, and its shading in Fig. l is intended toshow contrast of wood and metal. Spiders E, rigid with the cylinderinside the saine, are fast on a shaft F, supported in bearings on theframestandards, and the shaft is provided with a pulley G for adriving-belt. Vertical bars of the frame-standards are provided withlongi- (No model.)

l-I of a cylindrical brush I, and these bearings rest onadjusting-screws J, engaging threaded apertures in bosses fof saidstandards. The tufts of the brush are preferably Wire, and the verticaladjustment of said brush is such that said tufts touch against therasptooth face of cylinder C,- nuts g being run on the bolts c againstthe wings d of bearings e to clamp said bearings in adjusted position.

The cylinder-shaft F is provided with a pulley K at that end oppositethe pulley G, and the brush-shaft II is also provided with a pulley L ofabout one-half the diameter of pulley K aforesaid. A pair of idlers Mturn 011 bosses extending from the frame-standard adjacent to pulleys KL, and trained on these pulleys and the idlers is a belt N, thedisposition of this belt being such that the brush I is driven in adirection opposite that of the rasp-face cylinder C, against which ittouches, and owing to the difference in diameter of said pulleys K L thespeed of said brush is about twice that of said cylinder.

In pivotal connection with ears h of the standards A below the frontside board of the housing aforesaid are arms P, having offset lower endst', connected by spiral springsQ with said standards. The arms are madefast at their upper ends to a bar R and therewith constitute a pivotalclam p-frame normally held away from the adjacent side board of themain-frame housing by contraction of the springs Q, as shown in Fig. 1.

In practice a skin to be treated is caught fur side out at one endbetween the main and clamp frames, the latter frame being pushed overand held tight against said skin by the body of the operator. Theremainder of the skin is swung over the exposed surface of the rotatoryrasp-face cylinder C and held thereto by the hands of the operator,these hands being moved about on said skin to determine when the latteris evenly reduced to desirable thinness by contact with said cylinder,after which the aforesaid skin is reversed and the operation repeated.In case the skin is wider than thecylinder it is shifted froml time totime longitudinally of the same, the arches D aforesaid serving tosupport said skin when it overlaps the ends of said cylinder.

The revolution of the brush J at a higher speed than the cylinder and inan opposite ICO direction operates to keep the teeth of said cylinderclean and in cutting condition, said brush being moved upward from timeto time to compensate for Wear of its tufts.

Having thus described my invention, what I claim as new, and desire tosecu re by Letters Patent, is-

l. Ainaohiue for removal of spongy-leather substance from the iieshsides of tanned skins, the same consisting of a frame, arotatoryrasp-face cylinder, a spring-controlled clampframe in pivotal connectionwith the frame aforesaid, and a cylindrical brush having rotationagainst the rasp-face cylinder in a contrary direction.

2, A machine for the removal of spongyleather substance from the viiesllsides of LUDWIG C. SCHNEIDER.
